HP recently announced plans to eliminate brominated
flame retardants (BFRs) from casings of new products. BFRs are toxic chemicals
used to resist high levels of heat.
But Greenpeace China pointed out that other IT firms had taken the same step several years ago, and accused HP of falsely claiming environmentally friendly credentials.
Greenpeace said in a statement: "This small step still leaves HP way behind the rest of the electronics industry.
"Despite the fact that Greenpeace has been in dialogue with HP for almost two years, the company has yet to make a commitment on phasing out harmful substances."
But most used hardware still ends up in countries such as China and India, where low-paid workers are exposed to hazardous substances in Mad Max-style recycling plants.
Greenpeace said that HP rival Acer had a more environment-friendly track record with a commitment to announce a substitution plan to phase out all BFRs.
HP declined to comment.
