European pressure for a more sustainable palm oil production

April 24, 2017 by Jannick H. Schmidt

At their plenary session this month, the Members of Parliament voted on a resolution calling on the European Commission to work towards a European certification scheme for palm oil entering the EU market.

This political move comes at a most opportune moment for us here at 2.-0 LCA consultants; as we just this week are able to announce that our crowd-funded initiative: LCA of RSPO certified palm oil is up and running with currently 12 palm oil producing/using industries as members of the club. The initiative aims to compare the environmental profile of certified palm oil to non-certified palm oil in the market. Our project will be based on the already existing certification scheme by RSPO – but we hope to produce evidence, using life cycle thinking, that will also be relevant for a possible European certification scheme.

The Members of Parliament also call for a ‘phasing out of the use of vegetable oils that drive deforestation by 2020’. In our previous analysis of various biofuels, including several different vegetable oils, we found that a significant hotspot in the biodiesel product system is indeed indirect land use (deforestation) (Schmidt and Brandão 2013; Schmidt 2015). Regardless of which vegetable oils are used for biodiesel, our findings indicate that an increase in the use of biodiesel will lead to higher greenhouse gas (GHG) emissions, mainly because of the consequences of the indirect land use. On top of that, biodiesel from vegetable oils is associated with high impacts on biodiversity: deforestation caused via indirect land use changes.

In their press release the European Parliament also note that a major use for the European imports of palm oil is for biofuels. Kateřina Konečná, who edited the report on palm oil and deforestation of rainforests for the European parliament says that she hopes for a ‘total’ phase out of this use for palm oil. We have previously demonstrated that palm oil is the oil affected when there are changes in the demand for any unspecified vegetable oil (Schmidt and Weidema 2008). Therefore we believe that it is rather the entire market of vegetable oils for biofuels that needs to be discussed. Naturally, palm oil can be a suitable starting place for the discussion, and in this light we are hoping for a balanced response by European Commission.

In a market where everything is linked and palm oil is the additional supply for any demand for vegetable oil, a specific political ban on palm oil is not an efficient way forward. A better approach for the European Commission would be to reconsider the targets to increase the European use of biofuels in light of the evidence of its actual environmental consequences. Or at the very least to ensure that the sustainability criteria (See DG-Energy) for the European use of biofuels includes indirect land use effects. This is needed in order to actually reduce greenhouse gas (GHG) emissions – with consequences for the entire market of biofuels.

Instead of banning palm oil, we emphasize that a more efficient way to reduce the environmental impact is to collaborate with the palm oil industry. In fact, palm oil is the only major oil in the market, where there is a formalised way to make a difference with regard to deforestation, i.e. demanding oil from industries which ensure nature conservation within their concessions as well as in their surrounding communities.

Call for support to amend ISO 14044

March 15, 2017 by Bo Weidema

It will come as no surprise to regular readers of this blog that 2.-0 LCA consultants advocates a strict interpretation of the ISO 14040-series of standards for LCA to mean that a consequential modelling approach shall be used whenever the results are to be applied for decision support. Our advocacy for the consequential approach is based on its superior ability to reflect the physical and economic causality of changes in product systems.

The alternative modelling approach, which has come to be known as attributional, is nevertheless still in widespread use, even for product comparisons, supporting decisions that will shift demand between products, and to estimate the effect of increasing or decreasing system output. This points to a widespread lack of understanding of the limitations of attributional models. We have therefore spent quite some effort in explaining the difference between the two modelling approaches and their application areas.

These efforts include two recent scientific articles that contribute to solve the internal consistency problems in attributional modelling and clarify the importance of making the right choice of background data depending on the application area, based on an understanding of underlying reasons for the differences in results between the two modelling approaches.

Currently, ISO is investigating options for making amendments to overcome the largest problems in the current LCA standards. Through our national standardisation committee we have recently submitted a proposal to amend ISO 14044 on the topic of “Applications of LCA” aiming at clarifying how the requirements of the standard should be interpreted when applying each of the two approaches, both with respect to application areas, system boundaries, and co-product allocation. We urge all our readers to ask your national standardisation body to support that ISO initiates discussion on this proposed amendment.

Life-cycle under the desk?

February 23, 2017 by Bo Weidema

The employees of 2.-0 LCA consultants have access to a new piece of office equipment: An under-desk cycle. While we for many years have seen our colleagues standing at their height-adjustable tables, the new equipment allows for actively moving the legs, while seated at the table.

The investment in the new equipment is a spin-off of our recent study of how the 2015 Global Burden of Disease (GBD) study can be related to product life cycles, as part of our detailing of the impact pathways contributing to the social footprint (the report is available to members of our social LCA club). Here you can for example read about ”Inadequate physical exercise”:

“The GBD study attributes 35 million DALY (1.5% of GBD) to “low physical activity”, divided on ischemic heart disease (48%), diabetes (26%), stroke (15%), colon cancer (6%), and breast cancer (4%). This corresponds to the burden of disease for activity levels below the WHO minimum recommendation of 600 metabolic equivalent-minutes (MET-minutes) per week. Kyu et al. (2016) provides relative changes in risk per MET-minute/week, which can be translated into a DALY value per MET-minute/hour. We can define a pressure indicator for every hour of activity deviating positively or negatively from the average MET-level.”

This sparked the question: How much time do we actually spend on sedentary work at 2.-0 LCA consultants? And what can we do about it? Since none of the employees wants to work less to have time to exercise more, the only alternative solution is to exercise while working. A little more research led us to the desk-cycle as the currently most interesting option (but probably not the last) to prolong the life-cycle of our employees while they make life-cycles of products for our clients.

Let us talk about Hybrid LCA

January 26, 2017 by Michele De Rosa

Last November the SETAC scientific committee accepted our session proposal for the upcoming SETAC Europe Annual Meeting to be held in Brussels in May 2017 titled ’Advancements in Hybrid Life Cycle Assessment methodologies and analyses’. This session represents a much needed opportunity for improving current LCA methodology.

LCA is today a well-established science-based comparative assessment tool. As part of its integrated product policy the European Commission has concluded that LCA is “the best framework for assessing the potential environmental impacts of products currently available” (EU-IPP 2017). But these roses to Life Cycle thinking are not without thorns.

In the last 25 years practitioners have been mainly been conducting process-based LCAs of products or services, relying on a bottom-up inventory data collection. This has proven to be both expensive and time-consuming, because data had to be collected for each process in the life cycle. Furthermore bottom-up inventories may provide a rather incomplete picture of the product systems if cut-offs are used – resulting in an incomplete system with predefined boundaries.

In 2003 the SETAC Europe – LCA Steering Committee created a thematic group working on merging the strengths of traditional process-based LCA with economic Input-Output (IO)databases and to bridge the gap between the IO and the LCA communities. Here at 2.-0 LCA consultants, we have been engaged and involved in the Hybrid approach since its infancy.

IO databases have the great advantage to cover the complete economy including economic transactions and environmental extensions for all industries in the economy. Thus, IO databases provide a high level of completeness (eliminating a need for cut-offs). The IO databases are then supplemented with the high level of detail from the usual process-based data.

SETAC and the broader LCA community have increasingly considered this methodology, but for various reasons the progress has been languid, as tradition, knowledge gaps and the initial lack of regional IO databases acted as barriers for a more widespread used of Hybrid LCA.

I believe that this is about to change and the upcoming Hybrid LCA session at SETAC Brussels and the great interest for it by LCA practitioners certifies this change. In the session, chaired by me and Jannick Schmidt, I am expecting to see many contributions on integrating process-based data into macroeconomic IO databases. We will see some very interesting real applications of the Hybrid LCA framework and will appreciate the potential of this technique when applied to case studies. The session also has a dedicated poster corner.

Hybrid LCA has much to offer to give us a more complete picture – thus giving us the freedom to edge in on those aspects of the production-related impacts that are currently not sufficiently addressed in LCA. In social LCA for example we might identify unexpected hotspots often excluded in LCA, such as socio-economic impacts on local economies and people related to commerce and business services.

I hope to see you in Brussels in May for this and many other scientific discussions https://brussels.setac.org/
