It's been another big year for Greenpeace around the world, culminating in the Copenhagen climate summit. Take a look back on some of our best images and stories from 2009.

Want to know who's really pulling their finger out to give us products that cause the least environmental damage - then look no further.

Our ranking guide, published quarterly since 2006, shows clearly how the 18 top consumer electronics companies line up. But now we've produced a new chart showing which of those companies have eliminated the most harmful chemicals from their product ranges.

Roll over the stars in the chart below to see product details, and click the company name to visit their webpage about reducing harmful chemicals.

This article by Greenpeace climate campaigner Joss Garman (above) first appeared in yesterday's Guardian.

In his inaugural address, President Obama promised to "work tirelessly to … roll back the spectre of a warming planet", and to "restore science to its rightful place", adding: "Our time of standing pat, of protecting narrow interests and putting off unpleasant decisions – that time has surely passed."

You wouldn't know it from reading the Guardian this morning. Instead of sensing the spirit of "yes we can", you feel the familiar muscle of America's Big Carbon special interests. For months, US officials have been dampening expectations and lowering the bar on which climate measures could be expected from the new administration. This culminated yesterday in Obama signalling that he wants to delay a formal global climate agreement until next year at the earliest, rejecting the advice of his own science adviser, John Holdren.

Apple and Hewlett Packard get green points this month, as HP is rewarded in the latest edition of our Guide to Greener Electronics and Apple releases details of their greenhouse gas emissions. But the big points go to activist consumers for proving once again that public pressure creates positive change.

Greenpeace activists confront the tanker full of toxic sludge.

It reads a little bit like a John Grisham novel. An oil trading company at the heart of the city of London comes up with an innovative way to make massive profits by refining dirty gasoline. Only problem is, the process will produce a highly toxic sludge that is difficult to dispose of. Sure, they could pay an expensive fee to get it done in Rotterdam, but profits can be kept even higher by doing the dirty and dumping the caustic sludge in the city of Abidjan in the Ivory Coast, West Africa.

It's a plan designed to squeeze every last drop of money out of a dirty deal. But then the local population starts to suffer horrendous health effects, presumably from the toxic waste which has been dumped next to homes and workplaces. Whole areas of the city are evacuated, 15 people die, many more are permanently disfigured. People beseige health clinics demanding treatment. Read more »

When Hewlett Packhard staff arriving for work at the company's California HQ checked their phone messages yesterday morning, they found a recorded message from Star Trek's Captain James T Kirk waiting for them. Actor William Shatner urged them to question their boss, Mark Hurd, about the reasons why HP recently reneged on its promise to phase out dangerous toxic substances from its computers by 2009.

We've given HP, Lenovo and Dell - the world's biggest PC makers - a penalty point in our updated Guide to Greener Electronics, for backtracking on their commitments to eliminate PVC plastic and brominated flame retardants (BFRs) from their products by the end of 2009.

An old Philips TV at a scrap yard in Ghana

Last week we broke the shocking story about what actually happens to our electronic waste; instead of being safely recycled in the UK or Europe, much of it is instead being exported as 'second-hand goods' to places like Nigeria, China and India. Once there it's either sold for scrap, illegally dumped, or broken apart for recycling by some of the poorest people in the country, with no safety measures to protect them from the dangerous toxic chemicals like mercury, cadmium and lead which the e-waste contains.

As you may have seen on Sky News or the cover of the Independent this morning, our researchers have been conducting a three-year investigation in what really happens to electronic waste. The results show that, instead of being recycled responsibly like it's supposed to be, e-waste is being disguised as second-hand goods and being shipped of to (in this case) Nigeria. There, it's sold, scrapped or illegally dumped.

Acting on a tip-off, we launched our operation in collaboration with Sky Television to see just where some electronic waste was ending up. We took an unfixable TV, fitted it with a tracking device and brought it to Hampshire County Council for recycling. Instead of being safely dismantled in the UK or Europe, like it should have been, the council’s 'recycling' company, BJ Electronics, passed it on as 'second-hand goods' and it was shipped off to Nigeria to be sold or scrapped and dumped.

E-waste: as much as 4,000 tonnes is being dumped every hour

Our second greener products survey, "Green Electronics: the search continues", released today, assesses the progress made in 2008 by consumer electronics companies on their commitments to green their products. Fifteen major electronics brands submitted 50 of their most environmentally friendly new products - mobile and smart phones, televisions, computer monitors, notebook and desktop computers, and game consoles for evaluation. The survey assesses the products on their use of hazardous chemicals, energy efficiency, overall product lifecycle (recyclability and upgradeability) and other factors such as the promotion of environmental friendliness and innovation.
