For companies working with the CO2 Performance Ladder, the energy transition is in full swing. There is a strong increase in the generation of energy and the electrification of mobility and mobile equipment. Measures to switch offices off from gas are also on the rise. This and more can be found in the Report on the 2021 CO2 Performance Ladder Measure List. But whether things are moving fast enough remains to be seen.

The story behind the figures for 2021 is at least as interesting.'

The new Emissions Trading System ETS and the CO2 Performance Ladder

The Emission Trading System (ETS) has been in place since 2005 for electricity and heat generation, energy-intensive industries and aviation. But as part of the Fit for 55 package, the ETS is getting a major boost. The new EC-ETS proposal strengthens the overall target for the sectors concerned to a 43% reduction in emissions by 2030 (compared to 2005). At the same time, the phase-out of emissions allowances will be accelerated, and from 2027 there will be no free allowances for intra-EU aviation. Shipping to and from the EU will also gradually come to be covered by the system between 2023 and 2026.

Europe is ready for the CO2 Performance Ladder

Green public procurement (GPP) is developing rapidly across Europe, and the CO2 Performance Ladder can play a large role in boostin those efforts. These are the results of recent research conducted by the International Institute for Sustainable Development (IISD). Each year, European governments spend €1.8 trillion (14% of EU GDP) buying goods and services from the private sector but there is no requirement to consider the climate in these decisions. Shifting to green public procurement can result in a green revolution among companies and their supply chains, and the CO2 Performance Ladder can help.

Advancing GPP and low carbon procurement in Europe: Insights

Public procurement provides a key entry point for governments to change the trajectory of their greenhouse gas emissions, and to meet climate goals in line with their international commitments to the Paris Agreement, the Sustainable Development Goals, and - in Europe - to the European Green Deal. In the coming years, it is therefore essential that public procurement, which accounts for 15% of carbon emissions globally, becomes a driver of innovation and commercialization of low-carbon infrastructure, goods, and services. By Laura Turley, Liesbeth Casier and Ronja Bechauf from IISD. Read the original article here.

Public sector procurement activities are directly or indirectly responsible for 15% of global greenhouse gas (GHG) emissions, seven times the amount emitted by the entire aviation industry, according to a new report from the World Economic Forum and Boston Consulting Group (BCG). Around the world, the study finds, governments currently spend $11 trillion—or 15% of global GDP—on procurement every year, making the transition to green public procurement crucial for reaching net zero.

Sustainable superstructure renewal of industrial estate and yard tracks

For Charlotte Pars of ProRail, it is clear: as a contracting authority, you must use the influence you have to contribute to a more sustainable world. She shows that this can be done with little effort. For procuring entities which have perfected the basics, like ProRail, there are chances that require courage to take, but which also have the potential to achieve more results. In concrete terms, ProRail allows contractors to contribute to the design of projects and even to the standards that must be met. ‘By using the contractor's expertise, we can make more sustainable choices.’

SKAO publishes two harmonisation decisions on aviation and CPT companies

The Central College of Experts (in Dutch: CCVD)  of SKAO has published 2 new harmonisation decisions that are normative from now on. The first decision concerns the rules that apply when granting emission reductions to organisations that participate in renewable fuel programs for aviation. For example, it is described which sustainability requirements apply and which calculation rules must be applied. The second harmonisation decision states that companies that carry out CPT investigations belong in the category 'services', and not in the category 'works/supplies'. See the harmonisation acts for further explanation.
