1/ As #OceanCleanUp seeks to make a wave to strengthen its business model,it's important to remember that #plastic pollution is not just a waste issue,which is why a mandate was given to negotiate an agreement that covers the entire life cycle of #plastics.nature.com/articles/s4301…
2/ In one of the webinars that I visited recently to prepare for these negotiations, it was said, that there is now overwhelming evidence of health effects at every stage of #plastics lifecycle, nicely put together in the @minderoo report 👇#PlasticsTreaty

3/ In addition, at every stage of its life cycle, #plastics cause #greenhouse gas emmissions, which we super-urgently need to reduce to mitigate the #climatecrisis. This study estimated that plastic caused 4.5% of global #GHG emissions. #PlasticsTreaty

The idea of #CarbonReduction is to pay others to reduce emissions in your place. But your output remains in the system. One plus zero.

We understand the anger against politicians at #COP26 for delivering a weak, inadequate #ClimateChange agreement. But blaming individual decision-makers ignores the fact that the system rewards failure. Here’s how we tackle that reality. 🧵 (1/15)
Here’s the problem: the profits of the #FossilFuel economy are kept largely separate from its costs. That means that countries/companies/investors who generate products and burn fuels that cause #ClimateChange pocket the profits while others pay the price. 💵 (2/15)
As a result, #FossilFuels appear profitable, and there’s massive incentive for political and economic structures to treat these industries as wealth creators. Which creates incentives for climate denial, downplaying the role of the #FossilFuel industry, etc. (3/15)
Only a few days into @COP26, we’re already hearing global commitments and plans. This will all culminate in a day dedicated to the built environment next week. In the meantime, I’ll share my #COP26 thoughts in this thread.
