It’s nearly Christmas …. And as I write this it's even snowing outside the Greenpeace office, so maybe it’s time for a little goodwill and some good news.

Way back in 2008 we published a league table ranking the major tinned tuna suppliers in the UK on a number of environmental criteria. Back then big brands John West and Princes were languishing at the bottom of the pile. When we updated that league table in June 2009, we reported some significant process from many of the UK's big retailers – with Sainsbury’s, Co-op, M&S, Waitrose and Asda all increasing their commitments to more responsible sourcing of the tuna in their cans.

Tissues: not something many of us spend a great deal of time thinking about. As long as they does the job, what more do you need? But when you begin to consider where that paper has come from and the impact it has on forest areas, it starts to become a lot more interesting. That's why we've produced a new tissue product guide - search the guide to discover which brands of toilet roll, kitchen towel, and tissues are kind to forests as well as your nose.

Something that happened a few weeks ago but has slipped through the net is that Sainsbury's has announced an improved policy on light bulbs. By committing to phasing out those wasteful incandescent bulbs by 2010, they join Asda and Morrisons (who also recently shifted their stance) further up our league table. That still only gives them a D, but it leaves three supermarkets lower down - Tesco and the Co-op at E and Somerfield a disappointing F.

Meanwhile, there's been no further word from wooden spoon winners Woolworths since their CEO's response to our day of action, but we're still working on them. You may have been invited to sign a 'Seize the Light' flag outside you local branch, as groups of Greenpeace volunteers (like the Blackburn group pictured) have been collecting signatures to show Woolworths that their customers want them to help everyone improve their energy efficiency by getting rid of out-dated, inefficient light bulbs.

If you haven't emailed Woolworth CEO Trevor Bish-Jones, now's the time - everyone who's done so has received a personal response, and you could be one of those lucky people. Or if you fancy a bit of flag-signing, contact your local Greenpeace volunteer group and find out how you can help everyone make the switch.

Now in its third year, the Greenpeace Garden Furniture campaign has been shaking up retailers and manufacturers alike and resulted in sweeping changes to the industry.

It's back - the guide that shows which retailers are stocking forest-friendly garden furniture and how they rate against each other in our annual league table.
